“I let you travel the way you prefer.”

Bike and car sharing facilities – two more facets of the new way in which people want to live and work – are available all around, as well as the presence of numerous cycle paths. The building is also located close to several metro, tram and bus stops and the North Station is nearby.

For those who prefer to come by car, Quatuor is situated on the Brussels inner ring road, with the extensive national and international motorway network directly accessible.

You will get there with exceptional ease whichever mode of transport you choose. And that’s when the Quatuor experience, the ultimate work-life balance, comes in.

Designed for well-being and the environment


The specifications of Quatuor reflect the high standards of its owner Befimmo. From the very start of the design phase of Quatuor, everything has been thought to protect our valuable environment. This results in a BREEAM ‘Outstanding’ in the design stage for the entire site, a certification which takes into account the entire lifecycle of a building with a specific attention to the well-being of its occupants.
